Rna protein synthesis

  1. 1. RNA <ul><li>Ribonucleic acid </li></ul><ul><li>Single stranded </li></ul><ul><li>Sugar is ribose </li></ul><ul><li>Uracil replaces thymine </li></ul><ul><li>Types of RNA </li></ul><ul><ul><li>mRNA – messenger – transcription </li></ul></ul><ul><ul><li>tRNA – transfer - translation </li></ul></ul><ul><ul><li>rRNA – ribosomal – makes up part of ribosome </li></ul></ul>
  2. 3. DNA vs RNA <ul><li>Contains deoxyribose sugar </li></ul><ul><li>Is double stranded </li></ul><ul><li>Bonds A-T and C-G </li></ul><ul><li>Never leaves the nucleus </li></ul><ul><li>Contains ribose sugar </li></ul><ul><li>Is single stranded </li></ul><ul><li>Bonds A-U and C-G </li></ul><ul><li>Can leave the nucleus </li></ul>
  3. 4. gene expression <ul><li>mRNA copies DNA in nucleus – transcription </li></ul><ul><li>Takes copy to ribosome </li></ul><ul><li>tRNA brings amino acids to ribosome - translation </li></ul>Transcription Translation
  4. 6. Messenger RNA Codons
  5. 8. <ul><li>What does the chain of amino acids represent? </li></ul>Polypeptide Chain – A Protein Threonine Arginine Glycine Glycine Proline Asparagine Proline Alanine
  6. 9. Protein Review What is the monomer (subunit) for protein? What are the functions of protein? Name examples of proteins. amino acids structure or support; enzymes speed up chemical reactions muscles, hair, cartilage, nails
  7. 10. Mutations <ul><li>In somatic cells – not passed on to offspring, but could damage person </li></ul><ul><ul><li>UV radiation </li></ul></ul><ul><li>In gametes – occurring during fertilization, new gene is part of offspring </li></ul><ul><ul><li>Could make a non-functional protein </li></ul></ul><ul><ul><li>Could be a positive or negative effect </li></ul></ul>
  8. 11. Gene Mutations Substitution Insertion Deletion
  9. 12. Chromosomal Mutations Deletion Duplication Inversion Translocation
